饮食是炎症性肠病(IBD)的最关键因素之一。在进行基于营养的研究时应考虑整个饮食模式,以保持营养素之间协同作用的潜力。膳食指数是评价膳食质量的重要工具,我们调查了它与IBD的关系。包括14项关于基于指数的膳食模式与IBD之间关系的研究。6项研究显示了基于指数的膳食模式与IBD风险之间的关系,7项研究探讨了饮食指数和IBD的进展,1项研究调查了IBD患者指数与全因死亡率之间的关系。这些结果表明,地中海饮食的高分与IBD的风险和进展呈负相关。然而,具有高炎症潜能的饮食可增加IBD的风险并加重疾病活动.饮食评分有可能评估总体饮食质量与IBD风险和进展之间的关系。未来的随机对照试验需要证实饮食评分变化的影响。此评论已在www上注册。crd.约克。AC.英国/普朗生/作为CRD42020220926。
Diet is one of the most critical factors for inflammatory bowel disease (IBD). A whole dietary pattern should be considered when doing nutrient-based research to preserve the potential for synergism between nutrients. Dietary indices are important tools to evaluate diet quality, and we investigated the associations of it with IBD. Fourteen studies on the relation between index-based dietary patterns and IBD were included. 6 studies showed the relation between index-based dietary patterns and IBD risk, 7 studies explored the dietary indices and progression of IBD, and 1 study investigated the relationship between index and all-cause mortality in IBD patients. These results implied that a high score on the Mediterranean diet was negatively associated with risk and progression of IBD. However, a diet with high inflammatory potential could increase risk and aggravate disease activity in IBD. Dietary scores have the potential to evaluate the association between overall diet quality and risk and progression of IBD. Future randomized controlled trials are required to confirm the effect of the change in dietary score. This review was registered at www.crd.york.ac.uk/prospero/ as CRD42020220926.
